摘要： PROBLEM TO BE SOLVED: To prevent water content from staying so as to prevent suspended stringing from being electrically eroded by respectively dividing the opposite faces of a pair of blocks into center belts and both side belts, and forming stepped slopes of alternately angular symmetry on the surfaces of these three belts, in a supporting device supporting the suspended stringing of an electric railroad with the main pipe of movable brackets. SOLUTION: A suspended stringing insert groove A3 is formed on the center of a block A in which a center belt A1 is formed into a right descending slope and both side belts A2 are formed into left descending slopes. Using two such blocks A, one is used by changing phase by 180 deg. so as to set as a block B, and they are arranged on the upper and lower sides so as to form a rectangular parallelepiped. The blocks A, B are received in a U-shaped metal fitting, covered with a cover, and integrated by bolts. In this case, because the insert groove A3 is a semicircular groove, the walls are formed to be high on one side and low on the other side, and quickly naturally dried after rain water flows out along the slopes. At fitting the suspended stringing, the suspended stringing supported with high walls of the groove A3 at two positions is supported with a high wall in the reverse direction at the center, and hence the suspended stringing is prevented from dislocating.

摘要： PURPOSE: To provide a suspension wire protection cover which does not require another fitting work at a high place as it is easily fitted to a hanger ear and then is fitted to suspension wires integrally with this. CONSTITUTION: A suspension wire protection cover 1 is equipped with a main body 2 that is made of elastic synthetic resin and to be fitted so as to run along the inside surface of the upper portion of the belt slablike hanger bar 22 of a hanger ear 21 to be suspended at suspension wires H; and an elastic synthetic resin pinch-holding body 3 to be engaged with the upper portion of the main body 2 in dovetail joint type so as to pinch the upper portion of the hanger bar 22 between the main body 2 and it. This suspension wire protection cover 1 is fitted to the hanger ear 21 by applying the main body 2 to the upper portion inside of the hanger bar 22 and engaging the pinch-holding body 3 in dovetail joint type with the upper portion of the main body 2 with the hanger bar 22 interposed. This fitting work can be conducted on the ground. As the suspension wire protection cover 1 becomes integral with the hanger ear 21, work is completed only by suspending and fixing this at the suspension wires H.

摘要： PROBLEM TO BE SOLVED: To provide a pulley type tension balancer capable of easily adjusting a support position of a stopper arm regardless of a balancing device.
SOLUTION: The base end of a bracket 1 is pivotally supported by a first band metal fitting 12 fixed to a column P, the base end of the stopper arm 6 is pivotally supported by a second band metal fitting 13 fixed to the column P, the base end of an upper balancing bracket 8 is pivotally supported by a third band metal fitting 14 fixed to the column, and the upper end of a tension bar 11 pivotally supported in the intermediate part of the upper balancing bracket 8 on its lower end is pivotally supported by a forth band metal fitting 15 fixed to the column. Thus, the support position of the stopper arm 6 relative to the column P can be adjusted vertically independently of the balancing device 7.

摘要： PURPOSE:To make the pivotally fixed point height position of a pull-off constant even without an oscillation stopper pipe so as to enable a movable bracket for supporting a trolley wire to move horizontally and to be always on a horizontal line by superposing a connecting plate, having plural holes, on a pull plate provided with plural locking holes in correspondence with the holes of the connecting plate. CONSTITUTION:A connecting plate is formed into battledore shape. Holes for bolts 7 to be fastened to a bent part are bored in a shank part, and plural holes 3a-3d are bored in a plate part. A pull plate 4 is formed of a strip part and a sector part at the lower part. The strip part is provided with a hole 4a, an oblong hole 4b and a hole 4c bored from the upper part to the lower part, and the sector part is provided with holes 4d, 4e bored in circular arc shape. A pull-off 5 is pivotally fixed to the hole 4c at one end part while gripping a trolley wire by the other end. When the hole 4a and the upper end of the oblong hole 4b in the pull plate 4 are respectively overlapped with the holes 3c, 3d of the connecting plate, a bolt inserted into the hole 4e suppresses the pull-off 5 at the same push-up angle alpha, and the length L of a vertical line from the hole 3a to a horizontal line passing the hole 4c is equal.

摘要： PURPOSE:To facilitate the inspection of an electric rail-car line and the position adjustment of a trolley line by providing a support pipe having a downward bend section at one end fixed access-adjustably in the horizontal direction, and pivotally fitting a check pipe having a trolley line holding ear at the other end to the bend section into a scissors shape. CONSTITUTION:A support pipe 5 is arranged at the lower end of a lower bundle 2 fixed to a beam 1 via an insulator 3, and it is fixed with a band 4 access- adjustably in the horizontal direction. The support pipe 5 has a downward bend section 5a at one end, and a check pipe 6 is rockably supported at the lower end of the band section 5a with a pin 7. The check pipe 6 has an ear 6a at the other end, and a trolley line T is held here. When a new electric rail-car line is inspected by a track vehicle, the trolley line T can be easily adjusted to be located immediately below a catenary wire M by the access adjustment of the support pipe 5.
